Clyde Epperson Posted May 15, 2016 Report Share Posted May 15, 2016 I've read this is a catalytic converter gone bad from a bad coil. That I had changed with the computer also. If it is, is it the front or back converter? Quote Link to comment Share on other sites More sharing options...

Clyde Epperson Posted May 15, 2016 Author Report Share Posted May 15, 2016 Which one is bank 2? Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted May 15, 2016 Report Share Posted May 15, 2016 Luckily this is the radiator-side bank, the "easy" one. How long ago did you change the PCM and coil(s)? No other codes since then? Quote Link to comment Share on other sites More sharing options...
Clyde Epperson Posted May 15, 2016 Author Report Share Posted May 15, 2016 It was 2014 when I had the coil/pcm go out and had those fixed. At that time I didn't need and inspection. Quote Link to comment Share on other sites More sharing options...
Clyde Epperson Posted May 15, 2016 Author Report Share Posted May 15, 2016 I haven't pulled codes in a while to make sure. What is a good catalytic converter brandto get? Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted May 15, 2016 Report Share Posted May 15, 2016 I always went with OEM, most aftermarket warranties can be kind of iffy, at least with Eastern & Walker. I'd be ok with Magnaflow though. Hope your state does not require CARB compliance, might have to stick with OEM. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted May 15, 2016 Report Share Posted May 15, 2016 Any possibility that this might be the O2 sensor instead? Quote Link to comment Share on other sites More sharing options...
Clyde Epperson Posted May 16, 2016 Author Report Share Posted May 16, 2016 I thought that was a different code. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted May 16, 2016 Report Share Posted May 16, 2016 A code P0430 may mean that one or more of the following has happened: The catalytic converter is no longer functioning properly An oxygen sensor is not reading (functioning) properly There is an exhaust leak 1 Quote Link to comment Share on other sites More sharing options...
macbwt Posted May 17, 2016 Report Share Posted May 17, 2016 O2 sensor is really cheap compared to a cat. Might want to try it first. Then if not it at least you will have a new O2 to go with a new CAT. 3 Quote Link to comment Share on other sites More sharing options...
